L\u2019Aim-TTi LDH400P est un chargeur \u00e9lectronique DC programmable de 400 W con\u00e7u pour tester directement des sources d\u2019alimentation DC \u00e0 haute tension et des circuits de correction du facteur de puissance. Il offre une plage de fonctionnement \u00e9tendue allant de 10 \u00e0 500 V et de 0 \u00e0 16 A, avec une dissipation de puissance continue de 400 W \u00e0 28 \u00b0C et de 360 W \u00e0 40 \u00b0C. L\u2019LDH400P prend en charge les modes de fonctionnement \u00e0 courant constant, r\u00e9sistance constante, conductance constante et puissance constante, avec un r\u00e9glage de niveau haute r\u00e9solution et haute pr\u00e9cision. Son g\u00e9n\u00e9rateur de transitoires int\u00e9gr\u00e9 permet un contr\u00f4le de la vitesse de d\u00e9viation variable, tandis que la sortie de surveillance du courant permet de visualiser les formes d\u2019onde et le contr\u00f4le de la chute de tension variable permet d\u2019effectuer des tests sur les batteries. L\u2019affichage LCD r\u00e9tro\u00e9clair\u00e9 haute r\u00e9solution avec contr\u00f4le par touches permet une utilisation locale, tandis que la sortie analogique de niveau et le contr\u00f4le TTL permettent une utilisation externe. Les entr\u00e9es de charge sont homologu\u00e9es pour la cat\u00e9gorie CAT II (300 V), avec des bornes d\u2019entr\u00e9e avant et arri\u00e8re pour une connexion flexible. Les interfaces LAN compatibles USB, RS-232 et LXI fournissent un contr\u00f4le complet du bus, avec la possibilit\u00e9 d\u2019utiliser le GPIB en option. Le logiciel Test Bridge et les pilotes IVI permettent \u00e9galement des tests automatis\u00e9s. Sa capacit\u00e9 d\u2019alimentation haute tension de 400 W rend le LDH400P particuli\u00e8rement adapt\u00e9 \u00e0 l\u2019essai de sources \u00e0 haute tension telles que les PFC et les alimentations connect\u00e9es \u00e0 la ligne \u00e9lectrique.<\/p>","protected":false},"excerpt":{"rendered":"
